What is the common problem with dual flush toilets?
The Issue: Water Leaks
Over time, these valves may wear out and start leaking. The supply line connections are another frequent source of water leaks in tankless dual flush toilets. These connections link the toilet to your building's water supply and can become loose or damaged over time.

What height should a toilet fill valve be?
Adjusting the Water Level (Inside the Tank)
- Find the Mark: Look for the "CL" (Critical Level) mark on the fill valve or aim for 1 inch below the overflow tube top.
- Adjust the Valve:
- Twist Adjustment: Hold the valve's shank and twist the cap/float assembly; counter-clockwise raises the level, clockwise lowers it.
- Clip Adjustment: For clip-style floats, squeeze the clip and slide the float up or down the tower.
- Twist Adjustment: Hold the valve's shank and twist the cap/float assembly; counter-clockwise raises the level, clockwise lowers it.
- Test: Flush and check the new water level; repeat if necessary.

Standard Supply Line Height (Rough-In)
- Vertical: About 6 inches above the finished floor.
- Horizontal: About 6 inches to the side of the toilet's centerline.
- Note: Some one-piece toilets need a lower rough-in, so always check the manufacturer's specifications.

Key Things to Remember
- Don't Overfill: Water above the overflow pipe wastes water and causes the toilet to run constantly.
- Don't Underfill: Too low a water level results in weak flushes.
- Valve Height vs. Water Level: Adjusting the valve's physical height sets the range for the water level.

Do plumbers recommend dual flush toilets?
If you're looking for a way to cut down your water bill, dual-flush toilets are a step in the right direction. These toilets tend to use only about a third of the water that standard toilets use. This means your home uses less water, and you can save money on your water bill.Oct 10, 2025
